    Abstract: The invention relates to compounds of the general formula (I) in which A is a dye radical, optionally the radicals Y independently of one another are oxygen, sulphur, R -N or a direct bond, n is the number 1 or 2, the radicals R independently of one another are hydrogen or optionally substituted C1- to C4- alkyl and Z is a bridging member. The compounds according to the invention are highly suitable for dyeing textile material which contains hydroxyl groups.

    Abstract: The invention relates to metal complexes of compounds which in the form of the free acids correspond to the general formula I in which D is the radical of a complex-forming group in the o-position relative to the diazo component containing the azo bond, R is a disubstituted amino group, X is hydroxyl or amino, Y is hydroxyl or amino and Z is hydrogen, methyl, hydroxysulphonyl or D -N=N-, where D is phenyl optionally substituted by chlorine, bromine, methyl, ethyl, methoxy, ethoxy, nitro or hydroxysulphonyl. The compounds according to the invention are very highly suitable for dyeing leather.

    Abstract: The invention relates to compounds of the general formula I in which D is an isothiazole radical, R and R independently of one another are optionally substituted alkyl, alkenyl or cycloalkyl, and one of the radicals is moreover also hydrogen or optionally substituted aryl, R and R , together with the nitrogen, are a heterocyclic ring, R is nitro, cyano, alkylsulfonyl, carboxylic ester or optionally substituted carbamoyl or sulfamoyl and R is hydrogen or optionally substituted alkyl, cycloalkyl, aryl or hetaryl. The compounds according to the invention are particularly suitable for the dyeing of synthetic polyesters.

    Abstract: The present invention discloses substituted phenyl di and trisazo dyes free of reactive groups having two or three sulfonic acid groups, of the general formula: (I) wherein D1 is Z is hydrogen or D4-N=N-; D2 is phenyl substituted by hydroxyl, hydroxysulfonyl, chlorine or nitro, or is naphthyl substituted by hydroxy, hydroxysulfonyl or nitro, X, independently of one another, are hydroxyl or amino, D3 is phenyl which is substituted by hydroxysulfonyl, chlorine, bromine, methyl, methoxy, ethoxy, nitro, phenylamino, sulfophenylamino or nitrosulfophenylamino, or is naphthyl which is substituted by hydroxysulfonyl; D4 is phenyl which is unsubstituted or substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine, nitro, sulfamoyl or hydroxysulfonyl, or is naphthyl which is substituted by hydroxysulfonyl; and R2 is methyl, ethyl or allyl; the rings B and E may additionally be substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine or hydroxysulfonyl, with the proviso that D2 has a hydroxyl group ortho to the azo bond; or the iron, manganese, cobalt, chromium, nickel or copper complexes of this dye. These compounds, particularly in the form of their metal complexes are suitable for dyeing nitrogen-containing fibers such as wool, and preferably, leather. The present dyes yield very fast brown hues, in particular on retanned leather.
